Primary Production Sources and Bottom-up Limitations in Nearshore Ecosystems
Intertidal Temperature Data from Kachemak Bay, Prince William Sound, Katmai National Park and Preserve, and Kenai Fjords National Park
Intertidal Mussel (Mytilus) Data from Prince William Sound, Katmai National Park and Preserve, and Kenai Fjords National Park
Sea Otter Survey Data, Carcass Recovery Data, and Blood Chemistry Data from Southwest Alaska
Data for Gene Transcription Patterns in Response to Low Level Petroleum Contaminants in Mytilus trossulus from Field Sites and Harbors in Southcentral Alaska
Sea Otter Gene Transcription Data from Kodiak, the Alaska Peninsula, and Prince William Sound, Alaska, 2005-2012
Gulf Watch Alaska Nearshore Component: Monitoring Site Locations from Prince William Sound, Katmai National Park and Preserve, and Kenai Fjords National Park
Lack of strong responses to the Pacific marine heatwave by benthivorous marine birds indicates importance of trophic drivers
Gene expression and wildlife health: Varied interpretations based on perspective
Revealing the extent of sea otter impacts on bivalve prey through multi-trophic monitoring and mechanistic models
Brown bear–sea otter interactions along the Katmai coast: Terrestrial and nearshore communities linked by predation
Where land and sea meet: Brown bears and sea otters
Evidence of increased mussel abundance related to the Pacific marine heatwave and sea star wasting
Sea otter foraging behavior
Translocations maintain genetic diversity and increase connectivity in sea otters, Enhydra lutris
Sea otter population collapse in southwest Alaska: Assessing ecological covariates, consequences, and causal factors
Sea otter (Enhydra lutris) populations in southwest Alaska declined substantially between about 1990 and the most recent set of surveys in 2015. Here we report changes in the distribution and abundance of sea otters, and covarying patterns in reproduction, mortality, body size and condition, diet and foraging behavior, food availability, health profiles, and exposure to environmental contaminants
Ecosystem response persists after a prolonged marine heatwave
Spatial epidemiological patterns suggest mechanisms of land-sea transmission for Sarcocystis neurona in a coastal marine mammal
Trends and carrying capacity of sea otters in Southeast Alaska
